Spotted wing drosophila (D. suzukii) are invasive pests that penetrate the cherry skin and lay eggs during ripening. Drosophila attack both healthy and damaged fruit (UC IPM 2013), but prefer red to dark red colored fruit. By using traps and harvesting pollinizer tree fruit that ripen prior to the desired cultivar a grower can detect the presence of SWD, monitor fly levels, and indicate the need for insecticide application. However, insecticides are the only currently-effective control treatment (Van Steenwyk 2013).

Cherry leafhopper and mountain leafhopper are problematic because they are vectors of X-Disease/cherry buckskin. If present and not controlled, these leafhoppers can spread X-Disease rapidly within and between orchards. (UC IPM 2013).
